Patent CA-2013559-C (CA)
Title: Intelligent battery system
Inventor: BAUER GEORGE W
IPC: H02J7/00
Filed: 1990-03-30
Granted: 1995-10-31
Abstract: An intelligent battery system senses current flowing in the direction of charge current through positive and negative terminals and battery cells of a battery pack.  In response, a processor within the battery pack transmits battery parameter data to a separate output port of the battery pack.  The battery parameter data includes the state of charge of the battery cells, temperature data and the type of battery pack.  The processor also responds to specific data requests transmitted into the battery terminals by transmitting the requested battery parameter data.  The battery pack is also designed to minimize power dissipation of the processor.  When the battery pack is not subjected to either charge or discharge for a predetermined period, the processor is rendered into a "light-sleep" mode in which power dissipation is substantially reduced. The processor is awakened from the light-sleep either by a timer or hy charge or discharge activity to monitor the amount of charge or discharge and other battery parameters.

Title: Coded transmission system with initializing code
Inventor: TEZUKA KOJI
IPC: H03M7/30
Filed: 1990-05-25
Granted: 1996-09-17
Abstract: A coded transmission system wherein each bit of transmitted data having a logical value is coded depending on a coded result of a preceding bit, containing a sender-side apparatus, a transmission line, and a receiver-side apparatus. The transmission line connects the sender-side apparatus with the receiver-side apparatus. In the sender-side apparatus, a resetting bit and a message are generated; a code of a bit which is last transmitted and is necessary to code a bit which is to be transmitted next, is memorized in a first preceding code memorizing circuit, where the content of said first preceding code memorizing circuit is reset to an initial code responding to the resetting bit. A coding circuit receives the resetting bit and the message, coding each bit of the message in accordance with a predetermined coding rule and the content of the first preceding code memorizing circuit, and coding the resetting bit to a predetermined resetting code which is different from the codes used in the coding of the message. In the receiver-side apparatus, a code of a bit which is last received and is necessary to decode a code of a bit which is received next, is memorized in a second preceding code memorizing circuit. A resetting circuit resets a content of the second preceding code memorizing circuit to a predetermined initial code when receiving the resetting code. A decoding circuit decodes received codes corresponding to the message in accordance with the above predetermined rule and the content of the second preceding code memorizing circuit.
